Evaporator Liquid Distributor for Uniform Plate Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing evaporator liquid distributors result in non-uniform liquid charging of plates, leading to inefficient evaporation and temperature regulation due to uneven liquid distribution and pressure, which limits the evaporator's capacity and increases exit gas temperature.
Innovation Solution
A liquid distributor system that branches into multiple distributor lines with equal pressure loss, ensuring uniform liquid distribution across the evaporator body by connecting each line to multiple voids, with optional pre-distributor structures and microstructured plates for enhanced flow guidance and aperture plates for adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single large-volume cavity is used in the liquid distributor, then the structure is simple, but the liquid distribution to plates becomes non-uniform
Solution Approach 1:
The single large-volume cavity is divided into multiple smaller cavities (first cavity and second cavity) with separate feed lines. This segmentation allows independent control and optimization of liquid flow to different plate sections, achieving uniform liquid distribution while maintaining structural simplicity through modular design.
2Adaptability or versatility
If distributor lines have different lengths, then the evaporator can accommodate different plate configurations, but pressure loss varies causing non-uniform liquid charging
Solution Approach 1:
The distributor lines are designed with equal lengths and equivalent cross-sectional areas to ensure equal pressure loss across all lines. This equipotential design ensures that liquid reaches all plates at the same pressure, achieving uniform liquid charging while maintaining adaptability to different evaporator configurations through the modular cavity system.
3Quantity of substance
If the feed line has large cross-sectional area to supply all plates, then liquid supply capacity is sufficient, but pressure loss varies across distributor lines
Solution Approach 1:
The feed line is divided into multiple distributor lines (first distributor line and second distributor line) that branch from the feed line to different cavities. This segmentation maintains sufficient total liquid supply capacity while reducing pressure loss variations by creating multiple parallel flow paths with equalized characteristics.
4Device complexity
If liquid distribution is non-uniform, then the evaporator structure is simple, but evaporation efficiency decreases and temperature regulation becomes difficult
Solution Approach 1:
The distributor lines are designed with equal lengths and equivalent cross-sectional areas to ensure equal pressure loss across all lines. This equipotential design ensures that liquid reaches all plates at the same pressure, achieving uniform liquid charging while maintaining adaptability to different evaporator configurations through the modular cavity system.
